The Jaguars placed Burton, 24, on the reserve/retired list Wednesday. He had eight catches for 76 yards in four games for them last season, his third in the NFL.

Burton had a career-high five receptions for 42 yards in a Week 3 game at Seattle last season but reported concussion-like symptoms afterward. He missed the next five games, returned against Tennessee in Week 10 and suffered another concussion that later landed him on injured reserve.

A seventh-round draft pick out of West Texas A&M by the Vikings in 2011, Burton had seven catches for 73 yards and one touchdown over two seasons with Minnesota before getting cut at the end of training camp last year and getting claimed by the Jaguars.

He had one year remaining on his contract, with a non-guaranteed base salary of $645,000 in 2014.
